UK warns people with serious allergies to avoid Pfizer vaccine after two adverse reactions
LONDON (Reuters) - Britain’s medicine regulator has advised that people with a history of significant allergies do not get Pfizer-BioNTech’s COVID-19 vaccine after two people reported severe adverse reactions on the first day of rollout.
Starting with the elderly and frontline workers, Britain began mass vaccinating its population on Tuesday, part of a global drive that poses one of the biggest logistical challenges in peacetime history.
